[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a conveying device for PVC pipe processing, comprising a conveying component 1 and a driving motor, the driving motor providing power for the conveying component 1, a plurality of movable rollers 101 are rollingly connected to the inner side of the side plate of the conveying component 1, and the movable rollers 101 on the opposite sides of the two side plates correspond one to one, an elastic conveyor belt 102 made of rubber material is connected to the roller body of the movable roller 101, the driving motor is fixed on the side plate of the conveying component 1, and its output end is fixed to one of the movable rollers 101, the driving motor drives the movable roller 101 to rotate, thereby driving the elastic conveyor belt 102 to move, thereby realizing the movement of the PVC pipe 3 placed on the top of the elastic conveyor belt 102.

[0029] A plurality of pressing components 2 are arranged on the top of the conveying component 1, wherein the pressing component 2 includes two pressing rollers 205, and the pressing rollers 205 squeeze the tube bodies on both sides of the top of the PVC tube 3. In the present embodiment, the pressing rollers 205 are made of metal material, and the preferred material is stainless steel. Thus, after the pressing rollers 205 squeeze the tube bodies on both sides of the top of the PVC tube 3, since the friction between the PVC tube and the pressing rollers 205 is small, it is convenient for the elastic conveyor belt 102 to convey the PVC tube 3 under pressure. Moreover, since the elastic conveyor belt 102 is made of rubber material, the friction between it and the PVC tube 3 is large, thereby effectively preventing the PVC tube 3 from slipping when conveying the PVC tube 3.

[0030] In this solution, after the PVC pipe 3 is compressed, the middle part of the top of the elastic conveyor belt 102 will be elastically deformed. In order to prevent the elastic conveyor belt 102 from being out of contact with the movable roller 101 when the two sides of the elastic conveyor belt 102 are warped, Figure 2 As shown, a plurality of anti-skid grooves are provided on the roller body of the movable roller 101, and a plurality of anti-skid ribs 103 are provided on the inner side of the elastic conveyor belt 102, and the anti-skid ribs 103 are matched with the anti-skid grooves.

[0031] like Figure 3 and Figure 4 As shown, the pressing assembly 2 also includes a door-shaped frame 201, at the top of which a double-headed screw rod 202 is movably connected, and the threads on the rod bodies on both sides of the double-headed screw rod 202 are in opposite directions, the double-headed screw rod 202 on one side extends out of the door-shaped frame 201, and a knob is fixed on its rod body, and two sliders 203 are movably arranged at the bottom of the door-shaped frame 201, and the two sliders 203 are movably screwed to the rod bodies on both sides of the double-headed screw rod 202, that is, when the double-headed screw rod 202 is rotated, the two sliders 203 can move towards or away from each other, and a U-shaped frame 204 is arranged at the bottom of the slider 203, and the pressure roller 205 is movably connected to the U-shaped frame 204 through a connecting shaft.

[0032] In order to ensure that the double-headed screw rod 202 drives the slider 203 to move along the top limit groove when it rotates, a top limit groove is opened at the bottom of the door frame 201, and a top limit block 206 is fixed on the top of the slider 203. The top limit block 206 is adapted to the top limit groove. The top limit groove can be a dovetail groove, a center-shaped groove or other special-shaped grooves, and the corresponding top limit block 206 is a dovetail block, a center-shaped block or other special-shaped blocks.

[0033] To supplement this solution, when in use, the PVC tube 3 is placed in the middle position of the top of the elastic conveyor belt 102, and then the double-headed screw 202 is rotated by the knob. When the double-headed screw 202 rotates, it drives the two sliders 203 to move toward each other, so that the two pressure rollers 205 squeeze the two sides of the top of the PVC tube 3, thereby limiting the PVC tube 3 between the two pressure rollers 205 and the elastic conveyor belt 102, so that it can adapt to the clamping of PVC tubes 3 of various sizes. When the two pressure rollers 205 squeeze the PVC tube 3, the elastic conveyor belt 102 is deformed by force, and under the resilience of the elastic conveyor belt 102, the elastic conveyor belt 102 is in close contact with the PVC tube 3, effectively preventing the PVC tube 3 from slipping. Example 2

[0034] Since the strength of the PVC tube 3 is relatively low, in order to prevent damage to the surface of the PVC tube 3 during extrusion, Figure 4 As shown, an extension block 207 is fixed at the bottom of the slider 203, and a U-shaped frame 204 is movably arranged at the bottom of the extension block 207. Specifically, a bottom limiting groove is opened at the bottom of the extension block 207, and a fixed shaft 209 is fixed between the side walls of the bottom limiting groove. A bottom limiting block 208 is fixed at the top of the U-shaped frame 204, and the bottom limiting block 208 is movably plugged into the fixed shaft 209, and a spring 210 is fixed between the side wall of the bottom limiting groove and the bottom limiting block 208.

[0035] In this way, when the pressing roller 205 squeezes the PVC tube 3, the pressing roller 205 is subjected to the reverse force of the PVC tube 3, and the pressing roller 205 moves toward the outside of the PVC tube 3. At this time, the spring 210 is in a contracted state, thereby buffering the reverse force and avoiding damage to the PVC tube 3 due to excessive clamping force.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
